The following example continues the analysis of the data set Measure to illustrate how you can use PROC TPSPLINE to fit a spline model with a higher-order penalty term. Spline models with high-order ...

Estimation of support frontiers and boundaries often involves monotone and/or concave edge data smoothing. This estimation problem arises in various unrelated contexts, such as optimal cost and ...

Keep the number of knots small (usually less than ten, although you can specify more). A degree three spline with nine knots, one at each decile, can closely follow a large variety of curves. Each ...

Gaussian processes have recently become popular in the empirical learning community. They encompass many classical methods of statistics, e.g., radial basis functions or various splines, and are ...
